This is a 10R resistor which gave up its life to save the rest of the module. It was there exactly for when someone got their stripe the wrong way round.
How do I know? I looked at the NLC build guide for the squid axon.
Normally this task is undertaken by a diode, btw.
Should be straightforward to repair.
The difficult bit is desoldering it without ending up with a blocked hole. (Lol).
